i have been searching in the web a way to do a simple thing, but it seems that isn't very simple to do this, so lets go:

i have a action in my dashboard that "show all values" when determinated company are selected, i have 3 companies, when i select company 1 or 2 or 3 the action filter the values in others worksheets like a charm. But when i click again in the same campany, the filter will disapear because nothing is selected. I'm looking for a way to set a value when nothing is selected. For example, if i click in company 1, the filter will show me all values for that, but when i click again in company 1, i want that the filter set the value to company 3 and stay filtered for this value, so when i click again in company 1 or 2 the filter needs to filter too. My companies are displaying a list of values with a percentage, so i'm clicking in this list, and making the action with this

the scenario are different, i find a solution for the other topic via SQL, in this case i need literaly set a default value for the filter, doing this i will be able to get the result that i want. I know that its possible to set a default value to a Workbook that, when its opened, will filter to the last value that was saved before close the project. So what i need is almost the same, i only need that the dashboard filter a determinated value when nothing is sleected. Example: nothing is select, ok, so lets filter to the option 4, or if i want to change, i can change to option 5 or 6, doens't matter, i just need to set a default value (but i'm starting to think that's impossible to do this in tableau). Actually when i select nothing, the tableau SUM all values, have no filter.
